急！！！BQ24195 charge-boost切换时，PMID输出会不会中断？

TI专家好，

bq24195可以设计成：拔掉适配时，自动boost，保证PMID继续输出5V左右电压。但是我看到这里有个220ms延时，这是不是意味着切换会有220ms（或以上）的中断？这个有办法解决吗，或者有没有其他推荐方案代替。

谢谢！

1. BAT above BATLOWV threshold (VBATLOWV set by REG04[1])
2. VBUS less than BAT+VSLEEP (in sleep mode)
3. Boost mode operation is enabled (OTG pin HIGH and REG01[5:4]=10)
4. After 220ms delay from boost mode enable
